Abstract: An absolute path name and a command line of a process associated with a process operating on a business server are found from process information acquired from the business server. A standard process decision unit judges an OS standard process. An interpreter decision unit judges an interpreter name from the command line. A shared directory decision unit judges an executive file name located directly under a shared directory. A subdirectory decision unit judges a parent-child relation of an executive file directory from the absolute path name of the executable file. As a result, an application name recognition unit recognizes a name of an application.

Abstract: A method for rapidly executing a series of remote procedure calls between a client and a server, comprising an RPC optimizer (101) that inputs an IDL source code (103) and client source codes (102, 102?, . . . ) so as to define as a new remote procedure a group of remote procedures to be performed by the client in an additional server source code (107). In turn, the RPC optimizer outputs a new IDL source code (106) to which an interface of the remote procedure is added, and new client source codes (105, 105?, . . . ) modified so as to use the remote procedure. This reduces communications involving a plurality of remote procedures to a single communication pass, thereby implementing high-speed communication between the client and the server.

Abstract: When a system configuration is changed, a policy rule that should be modified as a result of the configuration change is modified without fail. A policy management apparatus 1 comprises a processing unit and a policy rule table 151 that stores at least one policy rule for each component of a computer system. For each component of the computer system, the processing unit performs a receiving step, in which a notification of a configuration change is received, a detection step, in which at least one component that is affected by the component configuration change received in the receiving step is detected, and a generation step, in which a policy rule corresponding to each of the components detected in the detection step is specified from the policy rule table 151 and a list of specified policy rules is generated.

Abstract: In order to change a policy while alarm-monitoring a production environment, during a production-environment operation, a method of controlling a computer system is provided, in which a policy is temporarily changed, thereby performing setting change. An agent transmits a monitoring result based on a first monitoring condition. A management unit generates a second monitoring condition based on a received change request. The agent transmits a monitoring result based on the second monitoring condition. The management unit holds information for correlating the first and second monitoring conditions with each other. Upon reception of a confirmation request for confirming the second monitoring condition, the management unit specifies the first monitoring condition correlated with the second monitoring condition based on the information. The agent which has received the deletion request stops the transmission of the monitoring result based on the first monitoring condition.

Abstract: In an information processing system, a configuration information management apparatus stores an identifier of a resource of a management target apparatus and a resource address of the management target resource, in association with each other. The management target apparatus stores destination information and the identifier of the management target resource, in association with each other, the destination information used when the configuration information management apparatus receives event notification from the management target resource. The management target apparatus transmits the identifier of the resource and a current (the latest) resource address when transmitting the event notification of the management target resource to the configuration information managing apparatus.

Abstract: A technique of performing concurrency control of policies is provided, which makes it possible to efficiently utilize resources of an overall information system. According to the present invention, a policy execution device creates a list of components of a application system which are influenced by execution of an action of a policy instance, for respective policy instances. If trigger conditions of another policy instance are newly met during execution of a policy instance, the policy execution device compares a list of components of the policy instance presently being executed with a list of components of the policy instance whose trigger conditions are newly met. If there are no common components in the lists, the policy execution device executes the policy instance whose trigger conditions are newly met, and if there are common components in the lists, the policy execution device suspends the policy instance whose trigger conditions are newly met.

Abstract: In order to execute a flow control and a congestion control in a hop-by-hop manner in a data communication among computers connected to different networks, in a data communication between a client A1 and a remote server B, a communication proxy of the remote server B is located in a local server A in an LAN to which the client A belongs. A communication packet to be routed to the remote server B is stolen (received) and passed to a transport layer. A TCP communication between the client A1 and the remote server B is divided into two; a communication between the client A1 and the communication proxy of the remote server B and a communication between the communication proxy of the remote server B and the remote server B.
